That concept is utilized in the development of star-delta and delta-star transformations that preserve the source-to-terminal (s−t) capacity function in a flow network. The usefulness of these transformations in reducing complex networks to equivalent series-parallel ones is illustrated by examples. The resulting series-parallel networks are easily solvable for the networks s−t capacity function, which is a compact expression of the probability mass function (p.m.f.) of the maximum s−t flow.</p></div>","PeriodicalId":101070,"journal":{"name":"Reliability Engineering","volume":"19 1","pages":"Pages 49-58"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0143-8174(87)90020-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77718447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
